Description

The proposed group of inventions relates to the field of housing and industrial construction, and more specifically to the design of hardware such as door handles and to methods for their manufacture.

There are various designs of door handles (see, for example, patents of the Russian Federation:

- for utility models NN 69126, 75682, 82743, 86637, 98770, 98771, 104604, 112241;

- for inventions NN 2158341, 2162129, 2166046, 2188921, 2233369, 2233370, 2235176, 2235840, 2240407, 2240410, 2241104;

RF applications for inventions NN 2002132047, 2002132078, 2002132079, 2002132080, 2002132313, 2002132314, 2003108336, 2003108380, 2003108389, 2003108391, 2003108393, 2003108394, 2003108395, 2003108338, 2003124376, etc.).

All of these handle designs are quite complex, which reduces the reliability of their operation, and also have low manufacturability and manufacturing on the door.

Closest to the claimed solution according to the technical essence and the achieved effect of its use is the design of the handle according to the patent of the Russian Federation for invention N 2104378, which consists of two symmetrical halves, which include the actual handles (wooden handles), tie rods and distance racks. In addition, each handle is equipped with angled hidden fixing screws and locking threaded plugs.

This handle is also complex in design and has a low manufacturability of manufacturing and mounting on the door, as well as injury when closing the door.

The task to which the invention is directed is to simplify the manufacture and installation of the handle, as well as to increase the reliability of its operation by simplifying its design.

This problem is solved using the technical result, which consists in increasing the manufacturability of the manufacture and installation of the handle by ensuring the unification of the elements of the handle and ensuring its original safe configuration in operation.

The specified technical result is achieved by the fact that in the well-known door handle, consisting of two symmetrical halves, each of which contains a wooden handle and remote racks,

firstly, each half of the handle is equipped with a single flat figured base having two identical in length and mirrored in configuration parts relative to the transverse axis of symmetry of the base;

secondly, the configuration of the handle racks is made in such a way as to ensure that in each half the wooden handle is offset from the longitudinal axis of symmetry of the base to the side above one of the edges of the base while ensuring that the axis of the handle is parallel to the longitudinal axis of symmetry of the base (which eliminates the risk of injury when closing the door);

thirdly, each rack is made in the form of a set of curvilinear flat plates of different sizes, and the adjacent contours of the curved sections of the adjacent plates are equidistant;

fourthly, in each half, at least one of the elements of the rack is equipped with a locking protrusion made interacting with the handle and preventing its rotation.

The invention is illustrated by illustrations in which:

- in FIG. 1 shows a top view of one of the halves of the proposed handle assembly;

- in FIG. 2 shows a side view along arrow A (see FIG. 1);

- in FIG. 3 is an end view with a cutout for showing a rack mount assembly to a base;

- in FIG. 4 shows the outer large safety and decorative end plate of the rack;

- in FIG. 5 shows an internal small plate with cutouts for the attachment points of the rack to the base and with a locking protrusion for the handle;

- in FIG. 6 shows the inner large decorative plate with cutouts for the attachment points of the rack to the base;

- in FIG. 7 shows an inner large decorative plate with holes for the handle and for rivets;

- in FIG. 8 shows a typical base in a plan view;

- in FIG. 9 shows a general view of a typical handle;

- in FIG. 10 shows a photograph of a general view of both halves of the proposed pen;

- in FIG. Figure 11 shows a photograph of a typical stand for both halves of a handle with the effect of simulating artistic milling.

Each half of the proposed handle consists of 2 mirrored racks - right 1 and left 2 (see Fig. 1), which are attached to the base 3 with screws 4 and square nuts 5 (see Fig 3), hidden in racks 1 and 2. The handle 6 from rotation is protected by the locking protrusions 7 (see Fig. 5), made on separate elements of the racks 1 and 2, which significantly increases the reliability of operation of the handle.

Each half of the handle is equipped with a single flat figured base 3 (see Fig. 1, 2, 8), which has two parts that are identical in length and mirror in configuration relative to the transverse axis of symmetry of the base.

Each rack is made in the form of a set of curved flat plates of different sizes, and the adjacent contours of the curved sections of the adjacent plates are equidistant. Racks 1 and 2 are made by means of a set of plates: the outer large safety and decorative end plate 11 (see Fig. 4), the inner small plate 12 (see Fig. 5) with cutouts for the fastening points of the rack 1 or 2 to the base 3 and with locking protrusion 7 for the handle 6, the inner large decorative plate 13 (see Fig. 6) with cutouts for the fastening points of the rack to the base 3, the inner large decorative plate 14 (see Fig. 7) with holes for the handle 6 and rivets 15 The plates are made by stamping from a metal sheet and fastened between engagement on a stamp with rivets 15. The plates 12 of racks 1 or 2 are made to be known to be smaller, which, when assembling the entire rack, leads to the effect of simulating artistic milling using a shaped cutter (see Fig. 11) and reduces the requirements for the accuracy of plate manufacturing. The plates 12 and 13 are made with grooves for laying the nuts 5 (see Fig. 3). The plate 11 is made without an opening for the handle 6 to protect the ends of the latter and without a groove for the nut 5. The plate 14 of the rack is made without a groove for the nut 5. Thus, the nuts 5 are closed on all sides, which improves the aesthetic appearance of the handle as a whole. Racks 1 and 2 are made of the same (unified) elements and are assembled in mirror order.

The handle 6 (see Fig. 9) is made of wood on a lathe using shaped cutters. It can be tinted, if necessary, under valuable wood species and varnished.

After all the component handles are ready, assembly takes place. The assembled racks 1 and 2 are put on the handle 6 on both sides, after which 4 racks 1 and 2 are attached to the base 3 using 4 countersunk screws.

Plates 11, 12, 13, 14 (see Fig. 4, 5, 6, 7) are cut out separately on the dies. Moreover, plates of the same size along the contour (for example, 13, 14) can be cut on one stamp if removable punches are provided. Then the plates are assembled on the mandrel in a certain order, inside the rack 1 (see Fig. 3) two standard square nuts 5 are laid and the racks are fastened again on the stamp using 4 rivets 15 (see Fig. 2). The second rack 2 is assembled similarly, only the plates are dialed in the reverse order. The design of the base 3 handles (see Fig. 8) is made in such a way that it can be cut down on the stamp for 2 hits with a flip. This technique makes it possible to produce different sizes of handles on one tool. After all the metal component pens are ready, they are sent for coating.

After all the component handles are ready, assembly takes place. The assembled racks 1 and 2 are put on the handle 6 (see Fig. 1, 2) on both sides. Moreover, the protrusion 7 on one of the plates (see Fig. 5) protects the handle from turning, which increases the reliability of operation of the handle. Then, using 4 countersunk screws 4 racks 1 and 2 are attached to the base 3.

Thus, the proposed handle is mainly (with the exception of the handle 6) made of sheet metal by stamping and includes a small number of standard parts, which makes it technologically advanced and economically viable for mass production.

The handle is fixed to the door using self-tapping screws (not shown in the illustrations).

The proposed pen is made by the following method proposed by the author.

There are various methods for manufacturing door handles, see, for example, RF patents for inventions NN 2186917, 2235176, 2240409, 2240410, 2241104, RF applications for inventions NN 2002132047, 2002132047, 2002132078, 2002132079, 2002132080, 2002132313, 2002132314, 2003108336, 2003 2003108389, 2003108391, 2003108393, 2003108394, 2003108338, 2003124376 and others.

- the manufacture of at least one handle from parts of a U-shaped bar;

- manufacture of supports (distance racks) of the handle;

- the manufacture of means for connecting the supports to the handle;

- the manufacture of means for securing the handle on the door.

This method, although it allows you to make door handles, but it is low-tech and inefficient.

The task to which the invention is directed is to simplify the manufacture and installation of the handle, as well as to increase the reliability of its operation.

This problem is solved using the technical result, which consists in increasing the manufacturability of the manufacture and installation of the handle by ensuring the unification of the original elements of the handle and minimizing the use of standardized elements (for example, expensive fasteners).

- manufacture of at least one handle;

- manufacture of supports (distance racks) of the handle;

- the manufacture of means for connecting the supports to the handle;

- the manufacture of means for securing the handle on the door,

firstly, each support (rack) is made in the form of a set of curvilinear flat plates of different sizes, and at adjacent plates, the outer contours of the curved sections are equidistant,

secondly, before assembling the supports, their flat plates are cut out on the dies, the base of the handle fastening means on the door is cut out on the stamp for two hits with a flip, then the plates are assembled on the mandrel, the nuts of the handle fixing means on the base are put inside the supports, after which the supports are fastened on the stamp with rivets,

- thirdly, the handle is made of wood on a lathe using shaped straight cutters with grooves, after which the handle is tinted for valuable wood species and varnished;

fourthly, all metal components of the handle are coated with powder enamel, for example, such as “Powder paint Interpon 700 Epoxy-Polyester RAL 9005 TR LF smooth matte 30%”.

Using the proposed inventions allows you to:

1. Significantly simplify the manufacture and installation of the handle, as well as increase the reliability of its operation by simplifying its design.

2. To increase the manufacturability of the manufacture and installation of the handle by ensuring the unification of the easy-to-manufacture original elements of the handle and ensuring its safe operation

3. To reduce the cost of manufacturing the handle while ensuring high reliability and ease of operation.
